I am new to Cloudflare so please forgive me in being very unfamiliar to it all. I have created an account and I am in the process of attempting to add a domain to Cloudflare, which excludes https:// and also the www. in the web address, yet it still comes back as invalid domain.
I have also contacted my ISP provider of this DNS following on this troubleshooting article I came across (source: I cannot add my domain to Cloudflare... – Cloudflare Help Center) and they have confirmed that the DNSSEC is disabled. I am none the wiser and would be grateful for some help & assistance here. The purpose of utilising Cloudflare is to provide an extra security layer to my website portfolio, so some guidance would be appreciated.
